Answer:
round cake - 82.42 in^2
rectangular cake - 114 in^2
Round cake:
d = 7 in
r= d/2 = 7 in /2 = 3.5 in
h = 2
The surface area of a cylinder is: A = 2pie r^2 + 2pie rh The surface are of the round cake (cylindrical cake) excluding the bottom is
Area = 2pie r^2 + 2pie rh - pie r^2
Area = pie r^2 + 2pie rh
Area = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2
= 38.46 + 43.96
= 82.42 in^2
Rectangular cake:
w = 6 in |= 9 in h = 2 in
The surface area of a rectangle
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is
A = 2wl + 2wh + 2lh - wl
A = wl + 2wh + 2lh
A = 6 * 9 + 2* 6 * 2 +2 *9 * 2
= 54 + 24 +36
= 114 in^2

Natalie paid $20.7 for 3 small pizzas and a salad which was $3.
a- Write an equation to represent the situation
b- solve the equation to find the cost of one pizza. Show your work
Answer:
Step-by-step explanation:
a) Let the cost of a Pizza = $ x
Cost of three pizza's = 3 *x = 3x
cost of 3 pizza + cost of a salad = $ 20.7
3x + 3 = 20.7
b) 3x + 3 = 20. 7 {Subtract 3 from both sides}
3x = 20.7 - 3
3x = 17.7 {Divide both sides by 3}
x = 17.7/3
x = 5.9
Cost of one pizza = $ 5.9

Question :-
A cylinder has a radius of 4.9 ft and a height of 7.8 ft. What is the surface area of the cylinder?Answer :-
The surface area of the cylinder is 390.8044 ft².[tex] \rule{180pt}{3pt}[/tex]
Diagram :-
[tex]\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{4.9 \: ft}}\put(9,17.5){\sf{7.8 \: ft}}\end{picture}[/tex]
Solution :-
As per the provided information in the given question, we have been given that the radius of the cylinder is 4.9 ft. The height of the cylinder is 7.8 ft. We have been asked to find or calculate the surface area of the cylinder.
To calculate the surface area of the cylinder, we will use the formula below :-
[tex]\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh \:\:}}[/tex]
Substitute the given values into the above formula and solve for surface area:
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh[/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(4.9 \: ft)^2 + (2)(3.14)(4.9\: ft)(7.8\:ft) [/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(24.01\: ft^2) + (2)(3.14)(38.22\:ft^2) [/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(75.3914 \: ft^2) + (2)(120.0108 \: ft^2) [/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 150.7828 \: ft^2 + 240.0216 \: ft^2 [/tex]
[tex]\sf:\implies \bf{Surface \: Area_{(Cylinder)} = 390.8044 \: ft^2}[/tex]
Therefore :-
The surface area of the cylinder is 390.8044 ft².[tex]\\[/tex]

The ratio of red to yellow paint is 4:3. If you use 24 pints of yellow paint, how many pints of red paint do you need?
Answer:
32 pints
Step-by-step explanation:
Given :-
The ratio of red to yellow is 4:3 .I use 24 pints of yellow paint .And we need to find how many pints of red paint will we use .So let us take that we used x pints.
According to the Question :-
[tex]:\implies[/tex] 4:3 = x : 24
[tex]:\implies[/tex] 4/3 = x/24
[tex]:\implies[/tex] 4 = x/8
[tex]:\implies[/tex] x = 8*4
[tex]:\implies[/tex] x = 32
Hence we will use 32 pints of red paint.

Emilia's inequality, I < 6 is Choose... because the number of hours is Choose... Emilia's number line is Choose... . The endpoint Choose... filled in and the number line Choose... of the endpoint
Given :-
Given :- Emilia pays $24 to rent a boat at the lake for up to 6 hours. She constructs the inequality and number line below to represent the number of hours .
Answer:
→ Emilia inequality for x number of hours = x ≤ 6 .
since, she pays $24 for upto 6 hours , she can use boat from 0 hours to maximum 6 hours .
therefore, Emilia's inequality x ≤ 6 is correct because the number of hours is less than or equal to 6 .
now, from image, we can see that, Emilia uses number line from 0 hours to 14 hours in number line .
But correct number should be from 0 hours to 1,2,3,4,5 and 6 hours only .
therefore, Emilia's number line is incorrect . The endpoint is filled in and the number line is greater than the endpoint.
Step-by-step explanation:
Answer: emilias inequality x<6 is correct because the number of hours is less than or equal to six. emilias Number line is correct. the endpoint is correctly filled in and the number line should be shaded to the left of the endpoint.

Answer: 39°, 72°, 45°, 150°
Step-by-step explanation:
A circle has 360 degrees. [tex]\frac{1}{360}[/tex] would be equal to 1°
1) [tex]\frac{39}{360}[/tex] would be equal to 39° based on the rule above ^^
2) This fraction has a denominator of 5. Turn the denominator into 360. We can do this by multiplying the bottom by 72, since 360 ÷ 5 = 72 (make sure to multiply the numerator by 72 as well!)
[tex]\frac{1*72}{5*72}[/tex] = [tex]\frac{72}{360}[/tex]
This is equal to 72°
3) Use the same method as before
[tex]\frac{1*45}{8*45}[/tex] = [tex]\frac{45}{360}[/tex]
This is equal to 45°
4) Use the same method as before
[tex]\frac{5*30}{12*30}[/tex] = [tex]\frac{150}{360}[/tex]
This is equal to 150°
